First this happened  ......and then after I took the picture I accidentally turned the saw on instead of closing the lid and got oil all over me.  Andrea  |

again ? !!
*sigh*
sorry about the blade. What caused it this time?
The oil shower is a learning experience!
( I have a note on the front of my saw, because I did the same thing TWICE when I first got it) -
the oil bath, not the bent blade
got a spare blade on hand?

( I have a note on the front of my saw, because I did the same thing TWICE when I first got it) - the oil bath, not the bent blade got a spare blade on hand? Yes it's happened again.....the bent blade and the oil shower. Dinosaur poop killed the blade. I've been having saw problems...I was actually going to message you about it to see if you ever had the problem but you were busy getting ready for company (Irma) so I didn't. I have another thread about that problem forum.rocktumblinghobby.com/thread/80259/problems it was getting through smaller rocks with no real problem so I tried a bigger one. When it was cutting, all of a sudden there was a big bang. The rock either slipped in the vice or it was getting jammed in the blade and then slipped not sure which. The rock was tight in the vise I checked it twice but it's roundish so it could have come loose. I dont have a spare. I need to order one but I really need to get the feed working before putting in a new blade. Andrea |

Yes the camera is fine. It's my phone it was in my pocket because I needed one hand on the lid and the other on the knob to turn it on .....which was the hand that was supposed to be releasing the lid so I could close it...lol. |

Meviva, I have started using wooden shims(wedges) to help clamp rocks that are rounded or have sloped sides. I had two different rocks slip on my 20 inch saw and was real lucky that there was no blade damage. We had a game room added to the house about a year and half ago. I saved whatever wedged shaped wooden pieces I could find and cut a few extra angles myself and keep them in a 1 gallon bucket by the saw. Have used as many as 3 different wedges on a couple of the rocks to aid the clamping. They can be a bit of hassle to hold in place while tightening the clamp but have not had a failure since.
I always test the clamped rock with real firm push pull with my hand, any slight movement detected and I re-do the clamping.

Andrea, from that other thread, it looks like you have already tried adjusting the clutch block, so have you removed it to check the threads on the lower half that run against the feed rod?
I can't believe that they would be worn out on a saw as new as yours, but I guess that's worth looking at. A new bronze clutch block can't cost too much, maybe replace it just to be sure ?
Have you called BD to talk with one of their saw guys?
Your belt is fine and tight isn't it? Wouldn't think that it is just the blade slipping, but checking the belt isn't hard.
The only problem I have had with mine (other than a couple oil showers from being forgetful) was the rear belt pulley was loose and moved outward on the shaft. Had to knock the pulley back in place, tap the key back in the keyway and tighten the allen screw that holds the pulley in place.
You have checked the set screw at the back of the feed rod that holds the coupling from the power feed box to the feed rod I assume. And the threads on the feed rod are fine?
I don't know... sure would give BD a call though.
Be very interested to know what the problem is once you figure it out. Good luck!

I think it might be worth taking that blade out and seeing if you can straighten it.
It looks to be a fairly simple bend that could come out with a bit of light tapping with a small hammer on a flat surface. Don't hit it hard or you will stretch the metal and never get it straight.

Is this a Raytech 10 inch saw? if so I had all kinds of issues on mine with the brass clutch. It was not wore out just would not engage. Finally took it apart and could not put it back together with the little spring. Gave up and no I just tighten the handle on the one screw down while pressing the threaded rod down till the it's tight each time I need to make a cut.
Also the clamping system is confusing, I always tighten the wheel nut on the adjustable side first to fit the rock, then the big wing nut on the same side. When they are tight then the slab-feed wing nut on the other side. That way you only have to loosen the slab-feed wing-nut 4 or 5 cranks and cut the next slab. You may have already figured all this out, but it took me a few frustrating attempts to secure a rock the first time I used it.
And those round rocks are always a problem to clamp, especially for cutting geodes in half as you have to clamp with less than half the rock in the vise, real prone to slipping. I have a geode holder a good friend made for me to use on the 20 inch that seems to be working fine with no slipping and it can accommodate geodes from about 3 inches up to 8 inches in diameter, and I can change a rock out in less than 20 seconds. It's too big to fit the 10 inch saw so I cut all my geodes/thundereggs on the 20inch.
Good luck
Henry

Yikes !Welcome to the big ole "line of dirty oil down the middle of yore shirt gang" Since I'm the hurried forgetful type, that's not an uncommon experience with me but I cut in Wally World baby oil so it ain't too bad. Very frustrating to trash a blade though cause the folks that repair them don't do it anymore....Mel

I have probably cut close to 1000 slabs in the year that I've had it. Every time I'm in the rock room I'm cutting something. I was thinking that I should replace the clutch but I'm afraid if I take it apart I won't be able to put it back together. I have a video that shows what the feed rod does when it gets stuck but I can't upload it with rock show maybe I'll try a different photo host. I will I'll check the other things you mentioned to see if they are the problem. Andrea |

HankRocks the saw is a Barranca Diamond HP14. I have used shims when clamping the rock in the saw. I didn't this time. The rock was roundish but not smooth. I always check the rock a couple of times to be sure it's tight, but something went wrong.

I am going to try and straighten the blade and use it while trying to I get my feed problem fixed. Thanks |

(Thought I had it tight enough),Agate slipped in vise,"BOOM" blade got pinched and bent.... Sometimes you just never know... |

Using shims is not always easy and you find yourself needing that 3rd hand especially with the vertically opening clamp on my 20 inch saw.
The other thought I had, that sometimes causes clamp failure, sharpness of the blade. They do need to be touched up now and then.
